Intermittent No start.

Joe; had a similar problem with a Volare'. Cranked but wouldn't start. After a few tries it almost started, but only when I let off the key. Aah ha. Tried that a few more times and it started. I let the car warm up fully to avoid a chance of stalling and to keep the family warm [and happy]. Drove home, put an old ECU unit in it the next day, and it fired right up. Put a new ECU unit in a week later. Put the old good ECU unit in the glove box with a ballast resistor, a phillips screwdriver, and a 7/16 box wrench. Never had to use them. Happiness is.
